I build high-scale iOS and Android features for Microsoft Teams.

At Microsoft India R&D, I build native iOS and Android experiences for Microsoft Teams used by millions of daily users. I architected ContentPicker in Swift end-to-end, shipped it through CocoaPods, and helped drive approximately 4.55M cumulative footfall with enterprise clients.

I improved Teams iOS file-preview P95 latency by 22%, from 5.4s to 4.2s, while raising reliability to 99.69%. I also re-architected FLORA file-preview entry points to increase iOS retention by 5% and delivered Android file-management capabilities across 4.3M+ menu opens.

I work across Swift, SwiftUI, UIKit, Objective-C, Kotlin, Java, and C++, combining mobile architecture with cross-functional delivery through Azure DevOps and Agile workflows.
